Something very strange (and nasty) happened today.
In short: my financial status, which was very wealthy last turn and was expected to grow even more this turn, seemed to have a NEGATIVE value!

Maeli, please fix this, because you know what happens when somebody runs in minus! (I got one very sad mail from the Kosmor Host, called "Finances", which is informing me that basically my whole economy is bankrupt!)

A little help for Maelstroem:

Several times already after integrating a sub I have noticed that my finances can not grow above certain threshold - the amount of money I had was suspiciously rounded.
Last turn I approached again that threshold, but I also sold a planet to someone for large amount of money. So, seems this time I succeeded to overcome that "money border". Surprisingly, the accumulated credits appeared to have one nasty "MINUS" in front of the sum!

What can be done? There must be a way my status from yesterday to be restored!?
I can give all details to Maelstroem if required.

Dang. Do you remember what your net gain/loss for today was on your finances page. If there was an integer overflow, then it should still report a gain (since the net gain/loss shouldn't be as extreme as the byte limit). Just the thought of an integer suddenly converting to its two's complement is rather nightmarish, but it seems somewhat likely.

that would depend on whether one was computed before the other, or simply daily diff = final - start (before extra moneys (integrating people, selling planets etc)) are calculated_________________Major alphabravo in the house Thalgados-Sissyhood

Sounds like an integer overflow, yep. There should have been an amount of protection against it (2 Gig Credit Limit), but that was obviously broken by that solar system sale.
The limit won't be necessary in the next version, but it still takes time.

All done (did not take too long, was distracted by another mail). Lowered the system credits limit to 1.8 Gig to extend protection against this.
The next gpu version will use 64bit integers for credits.
